After designing and printing my first key-fob I decided I needed some more. And this is the result. Then I thought I’d offer it to the community incase someone finds it useful.

It has a diameter of 4cm, so easily fits into a pocket. Of course it can be scaled up in Bambu Slicer if you need a larger version.

I have included two plates, one with an automatic colour change if you have an AMS and a second plate with a pause included, allowing manual colour change.

As an aside, the Celtic Knot, also known as the endless knot or mystic knot, is a symbol of eternity and interconnectedness in Celtic culture and mythology. Characterised by its loops with no start or end, the knot signifies the timeless nature of the spirit and the continuity of life, love, and faith. Often found in ancient Celtic arts, it symbolises the interconnection of life and the intertwining of the physical and spiritual realms. Its meanings can vary slightly depending on its specific style, but it generally represents unity, harmony, and the eternal cycle of life.
